Correct answer get brianliest ! which decimal is equivalent to the mixed number plotted at point r on the number line? a. 5.3 b. 5.375 c. 5.38 d. 5.4

B. 5.375

Explanation:
First, find what the value of R is.
R is between 5 1/4 and 5 1/2, and every two increments are a total of 1/4 so 1/4 ÷ 2 = 1/8 
5 1/4 + 1/8 = 5 3/8 
R = 5 3/8 

Now find what this value is in decimal form. We know it is 5 point something, so just divide 3 by 8 to find the rest of the decimal. 
3 ÷ 8 = .375 so 5.375 is your answer. 

B is your answer. hope this helps!
